Abstract
A kind of screw(-type) feeder, pass through fore bearing and rear bearing supports the main shaft with helical blade in housing, housing is provided with charging aperture and discharging opening, front-end of spindle stretches out outside housing, and front-end of spindle is connected with speed reducer output shaft by shaft coupling, and the power shaft of reductor connects motor, between fore bearing and helical blade front end, sealing device is set, sealing device, by rotating back-up ring and seal receptacle constitutes labyrinth-type excluder, rotates back-up ring and is fixed on main shaft, and seal receptacle is fixed in inner walls；It is in rotation back-up ring anterior locations at housing bottom and is provided with ash discharging hole, ash discharging hole arranges push-pull valve.The utility model sealing device and pump nozzle prevent material from flowing backwards jointly, by push-pull valve can with periodic cleaning flow backwards material and sealing device and bearing etc. are checked, can effectively reduce material refluence in course of conveying and pile up the damage to lower bearing, the maintenance cost of minimizing equipment, the service life of extension device.
Description
Technical field:
The utility model relates to a kind of screw(-type) feeder, with anterior bearing anti-tamper dress during especially a kind of inclination transport
The screw(-type) feeder put.
Background technology:
At present, it is common to use screw(-type) feeder, bearings at both ends fixed form be all by basic bearing block and seal dress
Putting composition, tilting in transportation at material, material can flow backwards along the gap of blade and tube wall and pile up in bottom, day amasss the moon
Tired meeting causes bad seals and then the damage bearing of anterior bearing, makes screw(-type) feeder faults frequent.
Content of the invention:
The purpose of this utility model is to provide a kind of screw(-type) feeder, overcomes this because material refluence accumulation is to anterior bearing
The problem causing damage.
The purpose of this utility model be achieved in that in housing pass through fore bearing and rear bearing support with
The main shaft of helical blade, is provided with charging aperture in the front portion of housing, and the rear portion of housing is provided with discharging opening, and front-end of spindle stretches out
Outside housing, front-end of spindle is connected with speed reducer output shaft by shaft coupling, the power shaft connection motor of reductor, at fore bearing and
Sealing device is set between helical blade front end, sealing device by rotating back-up ring and seal receptacle constitutes labyrinth-type excluder, rotation
Turning back-up ring to be fixed on main shaft, seal receptacle is fixed in inner walls；It is in rotation back-up ring anterior locations at housing bottom to arrange
There is ash discharging hole, ash discharging hole arranges push-pull valve.Sealing device can stop material to pass through the gap between housing and helical blade
The phenomenon flowing backwards, installs push-pull valve simultaneously on ash discharging hole, can be periodically to sealing device and bearing block inspection and discharge refluence
A small amount of material, prevents its damage to bearing block.
Rotating back-up ring is to connect cylinder in the neighboring of disk, and there is inside flanging at the two ends of cylinder；Seal receptacle is by office
Constituting in the clasp rotating back-up ring both sides, clasp is provided with and can accommodate the groove rotating back-up ring cylinder flanging.
On housing exterior walls, the position of corresponding sealing device arranges pump nozzle, the annular seal space phase of pump nozzle and sealing device
Logical.Utilize pump nozzle filling butter, sealing device is sealed further, is better protected from the refluence of material.
The utility model can efficiently reduce screw(-type) feeder material in course of conveying and flow backwards accumulation to lower bearing
Damage, reduce the maintenance cost of equipment, the service life of extension device.

End is connected with reductor 2 output shaft by shaft coupling 3, and the power shaft of reductor 2 connects motor 1, at fore bearing 4 and helical blade
Arranging sealing device 5 between front end, sealing device 5 is constituted labyrinth-type excluder by rotation back-up ring 14 and seal receptacle 13, rotates
Back-up ring 14 is fixed on main shaft 6, and seal receptacle 13 is fixed in inner walls, and rotating back-up ring 14 is to connect circle in the neighboring of disk
Cylinder, there is inside flanging at the two ends of cylinder；Seal receptacle 13 is made up of in the clasp rotating back-up ring 14 both sides office, and clasp is provided with
Can accommodate the groove rotating back-up ring 14 cylinder flanging, on housing exterior walls, the position of corresponding sealing device 5 arranges pump nozzle 12, note
Oil nozzle 12 communicates with the annular seal space of sealing device 5；It is in rotation back-up ring 14 anterior locations at housing bottom and be provided with ash discharging hole 9,
Ash discharging hole 9 arranges push-pull valve 10.Sealing device 5 and pump nozzle 12 prevent material from flowing backwards jointly, by inserting on ash discharging hole 9
The material that part flows backwards periodically can be cleared up and check sealing device 5 and bearing etc. by plate valve 10.
